I have a 1997 Dodge Stratus with Check engine codes as follows: Key ON,OFF,ON,OFF,ON codes 12, 34, 21, 55 I understand 12 is recent disconnected battery & 55 is end of test, but can't find definition of codes 21 & 34 any help would be greatly appriecated
Jeff: Go to "Allpar dot com" website and look for a complete list of codes for the older Chryslers. From mine I remember code 34 as having at least two posible meanings: a) EGR Solenoid circuit problema, and b) Speed control problema. Code 21 means a problema in the Oxygen sensor. Amclaussen.
